WIRE-JOINING TOOL. j

Application filed November 26, 1920. Serial No. 426,593.

T 0 all whom it may concern:

Be it known that SERAPIUNE F. BAU- WENS, a citizen of the United States, and a resident of Chicago, county of Cook, in the State of Illinois, has invented an Improvement-in Wire-Joining Tools, of which the following description, in connection with the accompanying drawings, is a' specification, like characters on the drawings representing like parts.

This machine relates to wire working and to tools'devices or machines for use in joining wires, wire bindings or wire ties on or about boxes, box parts, bales, bundles, packages or the like. Among other objects the invention is in- .tended to provide a tool or device adapted to readily receive ends of wires to be joined and produce a strong efiicient joindcr therebetween. ,Another object is to provide such a tool with means to preliminarily tension the wire aboutthe box or package. Still another object is to provide such a tool with means to sever the ends of the wires in such a manner as to leave them free of objection-' able sharp edges or points. V

' The invention will be clearly understood from the following description with refer.- cnce to one illustrative tool containing an embodiment of. the, invention shown in the accompanying drawings A simple form of hand tool is selected for illustration, it being understood, however, .that the invention is not limited to the specific illustrative form, nor to a hand tool.

.Referring to the drawings Fig. 1 isa side elevation of the illustrative tool with the jaws open to receive the wire ends to be operated upon.

Fig. 2'isa similar view seen from the left in Fig. 1 and showing the tool turned on its long axis at right angles to the position shown in Fig. 1. The position of the hand lever when the jaws of the tool are closed is shown in dotted lines.-

Fig. isan end view of the nose of the tool seen from A-A in Fig. 1.

Fig. 4; is a, similar view showing the aws partially closed.

.. Fig. 5 is a similar view showing the'jaws closed.

Figs. 6, 7, 8 and 9 are longitudinal sectional views of the twister jaws taken on the line B--B of Fig. 2, and sho'w.the position of the parts during difl'erelii, stages of the operation 'of the tool.

Fi 10 is a sectional view taken on the line 4201: Fig.8.

Fig. 11 is a perspective view of a corner portion of an ordinary wirebound box. The wires or wire ends on the lid and front side of which are to be tensionally joined to complete the continuity of the wire binding, and hold the lid firmly closed.

Fig. 12 is a perspective view illustrating the use of the illustrative-tool in joining the said wire ends.

Fig. 13 is a perspective; view of the box corner after the production of the joinder made by intertwisting the wire ends.

Fig. 14 is a similar view after the twisted wires have been hammered down against the side of the box.

The illustrative tool comprises a pair of relative removable jaws 1 and 2. carried between sideplates3- and 4-which areconj nccted and supported by cross mmbers'5 and screws 6-. Jaws 1 and 2 are mounted respectively on pins. 7 and 8 which are revolubly mounted in the side plates 3 and- 4 so that jaws l and 2am free to revolve between saidside plates. Said jaws areso. constructed and arranged that-when. expanded as shown in Figs'. 3 and6, an opening is provided to receive the ,wire' ends to be intertwisted and when contracted as, shown in Figs. 5 and 7 thejaws constitute.

a bore or barrel within which the wires are held side by side and intertwisted by rotation of the tool. The tool maybe ro tated in any suitable manner as for'instance by a brace 25 attached to side plates 3 and 4." For contracting or closing the jaws 1 and 2 upon the wire, a lever-9 is boltedito pin -7 which carries jaw 1, and jaws l and 2 are provided with intermeshing gears, 10 so that when lever 9 is swung from the posis tion shown in Fig. 1 to the posit-ion shown in dotted lines in Fig. 2, jawsl. and, 2 'will revolve untiltheir extremities engage one another as shown in Fig. 7 forming the bore or barrel above referred to.

Referring'to Figs. 7, 8, 9 and'lO, it will be noted that jaws l and 2 are provided respectively with gripping surfaces 11 and 12 constructed and arranged to close uponthe wires and grip them in such a manner as to prevent one wire from passing around the dther when the tool'is rotated. 'Said gripping surfaces are located a distancefrom the extremities of said jaws approximatel 9311181; w en to the length of a desired twist, an

the twist is completed said surfaces. are

adapted to wring'ofi, or severthewires at the gripping point in such a manner as to leave nosharp edges. 1

Thenose of the bore-or barrel formed by jaws 1 and 2 when closed, acts as a gauge to position the gripping surfaces 11 and 12 relative to the body of the box and alsd holds the wires together at the body of the box so that the nose and said jaws, and the gripping surfaees 11 and 12 function as a plurality of wires engagingmeans spaced apart a distance approximately equal to thedesired' length! of twist; with the wires so held, theformation of the twist, instead of proceeding from the gripping surfaces toward the box or from the box toward the gripping surfaces, takes place approximately. unitherefore, to prellminaz'zily tension the wire about the box or package before the ends thereof are twisted together. SI'ch'tensioning means comprises knurled surfaces 13 .and 14 formed on the innerfaees or the jaws -1 and 2 respectively, whichsurfaoeso grip the wires and draw the sameiuto'the tool when the 'aws are being swung to a closed position t us drawing the wire tightly about the box or package and tensioning the same. This preliminary tensioning is particularly advantageous when the wire I nding is loosely applied to the box or package, as it, enables theoperat'or quickly and easily to take up theslack in the wireand tension the same about the box or package before twisting the ends thereof to gether. 7' y In. the use of the tool for ioining, for instance, the ends of a wire b nding abouta box, the end portions of the wire are brought together'as'shown in Fig. 11, and the openingjorn'ied by jaws'l and 2 is slipped over the wire ends. The jaws, and'wires are then in the position shown in Fig. 6. The lever 9 is then swun to the position-shown in dotted lines in ig. 2 sw nging ajws 1- and 2 to the closed position shown in'Fi 7.

this operation the lgnurled eu 9.095, 13 an 14 draw the wire tightly over= {;the box corner and the grippingl'surfam's lland, itiol od by the nose of the tool relativetotheibox ide When iaws 1 and 2 are thus contracted has been slippedover wire en E: f ia emf guppmsfi e-mm between pp aces :11 and 12 and-forming a bor or rrel incaemg the-wire, as ahown-in'Fig. 7, the tool is rotated I. number of times by turning the handle of the brace to intertwist the wires between the box and grip surfaces; and when the twistis tow-1pm, that is, when the tightenin of its con-solutions develops a certamegree of resistance" a amstfurther twisting action as shown in 3'5 1 the continued rotation of the tool lacause the grip in surfaces to disrupt ordis ortjthe meta o the wires, and savers the terminaltof the twist as shown in Fig. 1 9, thus automatically disengaging the tool $0 from wire. 4 The "severing of the wires at the point of gripping may result from a combined squeezing, tearing, wrenching, shearing, and ewagmg, 'or aceordingto particular designs B5 of difi'erent' specific tools embodying features of this invention, it may depend mainly upon one or more of such factors. Apparently, the butt end of thetwlst functions as'an anvil-against which the wires are "swaged b the grippin surfaces. The tightness o fi the OOHVOlllOIlS of the twist, and the time of the severingoperation may "depend upoh :the :degree of'presure exerted upon the wire by the gripping surfaces or by the forni of the. grlpplng surfaces or 'both; that is, if thetool is so designed that the grippingsurfaces when contracted 'exerta heavy pressure on the wires, the severing t e wireswere more lightly gripped, and it has 11 'found in'practicethat if the gripping surfaces are so formed as to grip the wires with sharp or pointed surfaces,

the twist will not be as tight, and the wver- K53 ing operation will occur at an earlier period "in the operation of the tool.

For maintaining a constant pressure on the wires at the gripping point, and to facilitate handling the tool, an adjustable split clam 15 of any suitable design may be ro vide having a suitable notch into w ich the lever 9" may snapto lock the lever 9 when the jaws are close Themanner of handling the tool is illustrated in Figures 11 to-14. In these figures, 16 designates a wirebound box having wire binding 17 fastened thereabout by staples 1.8; the portions of said wire bin ing on adjacent separabl related box sides or sec- 2 tions e. g., the 11d and frontheving free end portions 19 and 20 which are to be tensionally connected to complete the-continuity of 'the binding and tightly close the-box. As

indicated-in'jliig. 11, the wire ends'19 and 20}? are brought together so that the tool may slipped'theieover." As shown in Fi g, thgj an Bib-and the-lever 9 has been back and operation will occur sooner than it would if we s g t 1,476,388
